Abstract: The invention herein is directed to a process for producing isocyanatoorganosilanes having low color and improved color stability over known isocyanatosilanes involving a neutralizing step in which a carbamatoorganosilane intermediate is neutralized with acid to a pH equal to or greater than 6.0, to the isocyanatosilane produced by said process and to coatings and numerous other industrial applications which are useful in numerous industries containing the isocyanatoorganosilane produced by the process.

Abstract: An electron beam tube apparatus comprises a plurality of electron beam tubes having a common output cavity. Power is coupled to the common cavity from the resonant cavities of the beam tubes, and is then fed to an output line. This arrangement permits the outputs of two or more beam tubes to be combined in a compact arrangement with little rf power loss. Previously, the signals from the output lines of respective beam tubes were combined. The output line may be transmission line or waveguide. The means for coupling signals between the cavities may comprise loops or irises, both of which may be selectively adjustable.

Abstract: A connector for making an electrical connection with a mating interface (17) includes a hollow conductor (1) within which is included a member (9) which is relatively movable with respect to the conductor (1). Resilient means (12), which may be a spring, is located between the conductor (1) and member (9). In a first state of the connector, the conductor (1) and member (9) are in a relative position in which the resilient means (12) exerts a force between them urging them together. Following a mechanical connection made between the member (9) and the mating interface (17), the connector is set in a second state in which the force applied by the resilient means (12) takes effect, moving the conductor (1) and member (9) towards one another to make an electrical connection between the conductor (1) and the mating interface (17). This allows a connection to be made with only minimal force and no torque, making it suitable for fragile connections.

Abstract: An electron beam tube such as a klystron includes a penultimate resonant cavity (22) located before the output cavity (14). The penultimate resonant cavity (22) is arranged to be inductively coupled, being resonant at a frequency which is slightly greater than a harmonic frequency. This provides increased sharpening of bunches of electrons arriving at the output cavity (14) giving increased efficiency at the output.

Abstract: A computer system including a chassis having a microprocessor mounted thereon. A system memory is coupled to provide storage to facilitate execution of computer programs by the microprocessor. An input is coupled to provide input to the microprocessor and a display is coupled to the microprocessor by a video controller. A mass storage is coupled to the microprocessor. A shielding body is mounted on the chassis. A pair of spaced apart contact members are attached to the shielding body. A main spring member is attached to at least one of the contact members. The main spring member includes an elongated beam offset from the contact members and a plurality of spring fingers interconnecting the beam and at least one of the contact members.

Abstract: An electron beam tube includes a unitary metal cylinder and a plurality of transverse walls located within it which define resonant cavities. As the cylinder is in one piece vacuum joints are only required at the ends of the structure. Drift spaces between the resonant cavities are enclosed within drift tubes which join two adjacent transverse walls. The inner diameter of the tube is stepped to facilitate assembly and accuracy of the structure. In use, an electron beam is generated and interacts with applied r.f. energy to produce amplification of an applied r.f. signal.

Abstract: An electronic valve includes a shell electrode which is mounted on a support in such a way as to provide a good continuous electrical contact therewith. The base of the shell electrode is flared and mates with a tapered portion of the support, and is held in contact therewith by means of a clamp.

Abstract: A method of making a pyrolytic graphite grid electrode for a high power transmitting tube includes the steps of holding a metallic grid electrode core between two copper blocks, heating the core to 1750.degree.C by passing an electric current through it and passing a carbonaceous gas over the heated core so that graphite is deposited thereon.Because the graphite thickness is reduced towards the copper blocks supporting the core, where the grid is to be used in a high voltage tube annular shields are provided around the supported ends of the grid.
